Application filed November 14, 1903- Serial No. 181,134.

To (12M wit/int [It may (:(llbCfJ/"i'b;

Be it known that l, JULIUs A. Pnnirixs, a citizen of" the United Stet-cs, residing at (hurdle, in. the count of Douglas, State of he, have invented an, liuprovenlent in itfiler-Bearings, oi which the following de scription, in co'nn ion with the acmnnpanying' drawings, is a specification, like lett us on the drawings representing like parts.

This invention has For its object to improve that class oi roller-bearings wherein a series oi lir-aririg-rollers contacting (iiau'ietrically at opposite points with the axle and box have interposed. between ,them a series of separztors that travel with he bearing-rollers in ii ir planetary motion about the axle.

my. present invention has been devised to ax ol' the bearing-rellers getting out oi par- -:isn1 with the longitudinal axisof the axle.

l have found in'practiee that any deviation. from true and correct parallelism between. i e:n*ingrollers and the axle dctrin iental he best preforinanre of the bearing, and iseqnently l have devised a novel bearing a part thereof a rider that sustains a pl urai it of bearing-n llers 1naintained therein in absolute parallelism. 'llhese bearingrollers, sus a ined in the rider with theirlongi "ul'linal axis in exact pz'irallelisin, serve as lr ders to maintain the hearing-rollers outside of the lenders and the separators in par allelis'in,

The endinost lmaring-rollcrs oi the rider contact with dill'erent sepuratm-rollers interposed l.)etween the said endinost rollers and other bearing-rollers of the of rollers which are sustained outside of the rider, and in this way it is possible to maintain all the beoringrollers and the separators in their true working relation with their longitudinal axes in. line with the longitudinal axis of the axle.

he -roller and to separator indicated by C i Fig. 3 is a plan view of the our in i i l with the top of the lmx on t lottcd line :r. if" 3 t shows a section similar to Fig. l, but with a modified form ol' rider; and Fig. dctarhed,

A represcius a steel tube that will surround and constitute part oi an axle. 'lhistubo presents two circular tracks 0 l", the inner llang'es c of which serve os raccways on which may travel the enlarged heads or ends a" of the separators r.

vB is a box shown as cut away at its exterior (see Fig. 3) to constitute a roller-bearingreecivinospace a, the side walls of which are beveled, as shown. at a.

'llhc bearingr llcrs ll contact with i the sleeve and also with the interior of the box, and the ends of the bearingwollers run close to the interned hinges c of the circular tracks C, carried bfthe steel tube. V

In. accordam'e with my invention IV have devised a rider l0; (shown detached in Fig. 2,) composed of side pieces 0 and connected ribs (2, the rider being thus made absolutely rigid. This rider sustains in Fig. 1 three leadenrolh i) ll l), and viewing higs. 1 and 2 the reduced portions 0 of the separators e'ontaet with the peripheries of the endmost leaderrolls D and l) oi the rider, the bearing-rollers D (shown as four) and the separators 0 (shown. as live) Contacting one with the other, as represented in the drawings, Fig. 1.

It will be understood that either the axle and its sleeve will rotate and the box remain at rest or the box ney rotate and the axle and its sleeve remain at lin 'eithe' ease the rider and the series of bearingwollers and separators will travel in the same direction as the rotative member travels, but at a slower speed, and as the bearing-rollers, the leader-rolls, and separators travel in their planetary motion about the longitudinal axis of the axle it will be understood that the rider sustaining the spindlesf of the leader-rollers D l) D maintains said spindles and the rollers surrounding them in substantially true parallelism with the longitudinal axis of the axle, and as these leader-rollers. cannot possibly deviate so that their longitmlinal axes can get out of parallelism with the longitudinal axis of the axle it 5 shows the rider loo follows that the bearing-rollers D are main- I have found in practice where the'bearingrollers and the separators are maintained in parallelism each with the other and with the longitudinal axis of the axle simply by contact of one roller with another that incase a bearing-roller loses ing is apt to be injured or destroyed or fails to operate properly.

In Figs. 4 and 5 I have shown a modified form of rider in which the two end pieces are united by two narrower ribs e the end pieces being adapted to sustain'two spindles carrying leader-rolls H H, whereas in Figs. 1 to 3. the rider sustains threeleader-rolls.

I prefer to sustain the leader-rolls in the rider by spindles extended through axial holes in each roll, the rolls and spindles being prevented from/ contacting one with the other by balls as provided for in United States Patent No, 664,820, dated December 25, 1900 but I consider aswithin the scope of my present invention the sustaining of the leader rollers of the rider in any usual manner so that they may rotate therein and in arallelism one with the other v nstead of the particular form of separators shown I may substitutewithout departing from my invention any usual form of separator that is commonly interposed between bearing-rollers having a planetary motion and applied loosel between an axle'and box. I have omitte from Fig. 4 some of the rollers D and separators, as they are shown in yet be kept its parallelism the bear- I It Will be understood that the steel tube A forms part of the axle, which is shown insection-lines only in Fi 1 and designated A.

Having describe my invention, What I claim, and desire to secure by Letters Patent, is

1. In a roller-bearing, an axle, a box, a rider, a plurality of leader-rolls sustained therein, and a series of detached bearingrollers and separators maintained in parallelism with and by said leader-rolls.

2. In a roller-bearing, an axle, a box, a se ries of bearing-rollers and separators interposed betweensaid axle and box, a rider, and a plurality of leadererolls mounted therein, said leader-rolls maintained with their axes in parallelism serving to maintain the axes of the bearing-rollers and separators in parallellSlIL' 3. In a roller-bearing, rider, a plurality of leaderrolls sustained therein, and a series of detached bearingroll ers and interposed separators, said detached rollers and separators traveling with the rider and its leader-rolls in their movement about the longitudinal axis of the elxle.

In testimony whereof name to this specification. in the presence of two subscribing witnesses.
